目的 :探讨口服碘番酸造影 CT诊断胆囊息肉样病变和阴性结石的价值。方法 :回顾性分析我院经病理证实的 18例胆囊息肉样病变和 7例阴性结石的口服胆囊造影 CT表现。结果 :胆固醇息肉 8例 ,表现为胆囊内多发或单发颗粒状充盈缺损 ,直径较小 ,0 .2～ 0 .5 cm ;炎症性息肉 4例表现为带蒂或无蒂的点状或细条状充盈缺损 ,直径 0 .5～ 1.5 cm;腺瘤样息肉 5例表现为单发结节状充盈缺损 ,直径 0 .6～ 0 .9cm;腺瘤恶变 1例表现为体积较大 ,基底部较宽的结节 ,直径 2 .0 cm;阴性结石 7例表现为单发或多发的大小不一的类圆形低密度影 ,CT值 - 12 0～ 13 HU ,直径 0 .5～ 3.0 cm。结论 :口服胆囊造影 CT是诊断胆囊息肉样病变和阴性结石的可靠方法之一 ,病变大小对病变的性质诊断有较大的帮助
Objective: To investigate the value of oral iodine acid contrast-enhanced CT in the diagnosis of polypoid lesions of gallbladder and negative stones. Methods: A retrospective analysis of 18 cases of pathologically confirmed gallbladder polypoid lesions and 7 cases of negative stones in the performance of oral cholecystography CT. Results: Cholesterol polyps in 8 cases showed multiple gallbladder or single granular filling defect, the diameter is small, 0.2 ~ 0.5 cm; inflammatory polyps in 4 cases showed pedunculated or pedicle-like punctate or strip Filling defects, diameter 0.5 ~ 1.5 cm; adenomatous polyp in 5 cases showed single nodular filling defect, diameter 0.6 ~ 0. 9cm; adenoma malignant lesions showed a larger volume, the base of the Ministry Wide nodules, diameter 2.0 cm; negative stones in 7 cases showed single or multiple sizes of different round low density, CT value - 12 0 ~ 13 HU, diameter 0.5 ~ 3.0 cm . Conclusions: Oral cholecystography CT is one of the reliable methods to diagnose polypoid lesions and negative stones of gallbladder. The size of lesion can help to diagnose the nature of lesions
